Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.00466 |
| Opus 5.5 | $0.00024 | $0.00186 |
| Sonnet 5.5 | $0.00012 | $0.00093 |
| Haiku 4.5 | $0.00006 | $0.00047 |
Grade A, and why
youtube scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
YouTube Skill
Extract information and transcripts from YouTube videos via yt-dlp and youtube-transcript-api.
When to Use
✅ USE this skill when:
- "What's this video about? https://youtube.com/watch?v=xyz"
- "Get the transcript of this video"
- "Search YouTube for Python tutorials"
- "Video title, duration, and description"
- User provides a YouTube URL and wants metadata or transcript
When NOT to Use
❌ DON'T use this skill when:
- Downloading videos or audio → use yt-dlp directly with download opts
- Live streams → transcript availability may be limited
- Private or unlisted videos → access may be restricted
Usage/Commands
python {skill_path}/youtube_info.py URL [command] [options]
Commands:
info(default) — video title, duration, views, descriptiontranscript— full transcript/subtitlessearch— search YouTube for videos (uses URL arg as search query)
Options:
--lang en— transcript language (default: en)--format json— output as JSON--max 5— max results for search (default: 5)
Examples
- "What's this video about? https://youtube.com/watch?v=xyz" →
python {skill_path}/youtube_info.py <URL> info - "Get the transcript of this video" →
python {skill_path}/youtube_info.py <URL> transcript - "Search YouTube for Python tutorials" →
python {skill_path}/youtube_info.py "Python tutorials" search
Notes
- Install dependencies:
pip install yt-dlp youtube-transcript-api - Transcript availability depends on whether the video has captions
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

youtube is a skill published in the GitHub repository ericwang915/PythonClaw (45 stars, last pushed 10d ago), licensed MIT. It adds 61 tokens to every session and 466 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
